How to Measure a TV:

Tools required:

All you need to measure a TV accurately is a measuring tape and something to jot down your notes. Use a level to make sure the TV is positioned properly while taking measurement.

Measuring the diagonal screen size:

Place the end of the tape measure at the bottom left corner of the TV screen (not including the bezel), and extend it diagonally across the screen to the top right corner. Note the measurement in inches as the screen size. This will help you compare the size of the TV to the advertised screen size.

Measuring a TV diagonally

Measuring the bezel:

To measure the bezel:

  1. Place the end of the tape measure at one edge of the TV screen and extend it horizontally to the other edge of the screen.
  2. Subtract the screen size from this measurement to find the total width of the bezel.
  3. Repeat this process vertically to determine the total height of the bezel.
  4. Note these measurements, as they will help you understand the overall dimensions of the TV.

Measuring overall dimensions (HxWxD):

To measure the overall dimensions of the TV:

  1. Start by measuring the width.
  2. Place the end of the tape measure at the left edge of the TV (including the bezel) and extend it horizontally to the right edge.
  3. Note this measurement as the overall width of the TV.
  4. Measure the height by placing the end of the tape measure at the bottom edge of the TV (including the bezel) and extending it vertically to the top edge.
  5. Note this measurement as the overall height of the TV.
  6. Measure the depth by placing the end of the tape measure at the front edge of the TV and extending it to the back edge.
  7. Note this measurement as the depth of the TV.

Understanding TV Sizes and Dimensions: Screen size vs. TV size

Diagonal screen size:

The advertised size of a TV, such as 32-inch or 65-inch, refers to the screen’s diagonal measurement from one corner to the opposite corner. This number gives you an idea of the general viewing area, but it’s essential to note that it doesn’t account for the entire dimensions of the TV, including the bezel and stand.

Bezel and its impact on overall dimensions:

The bezel is the frame surrounding the screen of the TV. While some TVs have slim bezels, others might have thicker ones, which can impact the overall dimensions of the TV. When considering the size of a TV for a specific space, it’s crucial to factor in the size of the bezel, as it will affect the total width and height of the unit.

Reading manufacturer specifications

Screen size:

When browsing for TVs, always take note of the advertised screen size, which is the diagonal measurement. This will give you a general idea of how large the screen is, but remember to consider other factors like the bezel and stand for a complete understanding of the TV’s dimensions.

Dimensions (HxWxD):

Manufacturers typically provide the dimensions of a TV, including its height, width, and depth. These measurements are important when determining whether a TV fits a specific space. Be aware that some manufacturers may include the dimensions with the stand, while others may only provide the ones without.

Including or excluding stand:

The TV stand can significantly affect the overall height and depth of the TV. When reading the dimensions provided by the manufacturer, note whether the measurements include the stand or not. If you plan on using a wall mount or have specific height requirements, this information will be crucial in selecting the right TV.

How to Choose the Right TV Size for Your Space

Measuring your space:

Before purchasing a TV, measuring the space where you plan to place it is crucial. Measure the area’s width, height, and depth to ensure the TV will fit comfortably. Be sure to consider any obstructions, such as doors, windows, or other furniture that may affect the placement of the TV.

Considering the type of TV stand or mount:

Think about whether you want to use a TV stand or a wall mount for your TV. If you plan to use a stand, ensure that it can support the weight and dimensions of the TV. If you’re opting for a wall mount, make sure it’s compatible with your TV’s VESA pattern (the standardized mounting pattern on the back of the TV) and that it can handle the weight of the TV.

Factoring in viewing distance:

To ensure an optimal viewing experience, consider the recommended viewing distance for the TV size you’re interested in. Generally, the minimum viewing distance should be 1.5 times the diagonal screen size, while the maximum viewing distance should be 2.5 times the screen size. For example, if you have a 55-inch TV, the ideal viewing distance would be between 6.9 feet and 11.5 feet. Keep this in mind when deciding on a TV size for your space.

Evaluating the layout of your room (windows, furniture, etc.):

Take into account the layout of your room when selecting a TV size. Consider the placement of windows, as glare from sunlight can affect the viewing experience. Additionally, think about the arrangement of your furniture and how it will impact the viewing distance and angles. Considering these factors, you can choose a TV size that complements your room’s layout and enhances your viewing experience.

The Impact of TV Size on Viewing Experience:

Viewing distance recommendations:

As mentioned earlier, the ideal viewing distance for a TV depends on its screen size. To calculate the minimum and maximum recommended viewing distances, multiply the diagonal screen size by 1.5 and 2.5, respectively. Following these guidelines will help you select a TV size that provides a comfortable and immersive viewing experience without causing eye strain or discomfort.

Screen resolution and its relationship to size:

The resolution of a TV refers to the number of pixels displayed on the screen, which impacts the image quality. A higher resolution results in a sharper and more detailed picture. When selecting a TV size, it’s essential to consider the screen resolution. A higher resolution, such as 4K or 8K, is recommended for larger TVs to maintain image quality. Conversely, smaller TVs with a lower resolution, such as 720p or 1080p, can still provide a satisfactory viewing experience.

The importance of aspect ratio:

The aspect ratio of a TV is the ratio of its width to its height. The most common aspect ratio for modern TVs is 16:9, ideal for widescreen content. When selecting a TV size, consider the aspect ratio of the content you watch most often. For example, suppose you primarily view films in a wider format, such as 21:9. In that case, you may want to consider a TV with an ultra-wide screen to fully appreciate the cinematic experience.

Balancing size with other factors (sound, design, etc.):

While TV size is an important factor, it’s essential to consider other elements that contribute to the overall viewing experience, such as sound quality and design. A larger TV may offer a more immersive visual experience but may not have the best built-in audio system. In this case, invest in a soundbar or home theater system to enhance the audio quality. Additionally, the design of the TV, including its bezel and stand, can impact its aesthetic appeal and compatibility with your room’s décor. Remember to balance these factors when selecting a TV size to create the best viewing experience.

Wall Mounting and Cabinet Considerations:

Types of wall mounts:

Several types of wall mounts are available, each offering different levels of flexibility and movement. Some common options include:

  1. Fixed mounts: These mounts hold the TV flat against the wall without tilt or swivel capabilities. They are the most straightforward and affordable option.
  2. Tilting mounts: These mounts allow for a limited vertical tilt, which can help reduce glare and improve viewing angles if the TV is mounted higher than the ideal viewing height.
  3. Full-motion mounts: These mounts offer the most flexibility, allowing the TV to tilt, swivel, and extend from the wall. They are ideal for rooms with multiple seating areas or changing lighting conditions.

Measuring for wall mounting:

When preparing to wall mount your TV, measuring the dimensions of both the TV and mounting area is essential. Additionally, consider the VESA pattern (the standardized mounting holes on the back of the TV) and the TV’s weight to ensure you select a compatible wall mount. Be sure to measure the desired height of the TV from the floor and ensure that the mounting location provides ample space for the TV’s width and height, including the bezel.

Cabinet dimensions and ventilation:

If you plan to place your TV in a cabinet or on a shelf, it’s crucial to measure the dimensions of the space to ensure the TV will fit comfortably. Remember to consider the stand’s dimensions when measuring the cabinet or shelf. Also, ensure enough space around the TV for proper ventilation, as insufficient airflow can cause overheating and damage the TV over time.

Tips for a safe and secure installation:

When installing your TV, whether on a wall mount or in a cabinet, follow these tips for a safe and secure setup:

  1. Use a stud finder to locate wall studs for a secure and stable installation when wall mounting.
  2. Ensure that the wall mount or cabinet can support the weight of the TV.
  3. Use the proper hardware and tools, and follow the manufacturer’s instructions for installation.
  4. Consider hiring a professional if you need clarification on the installation process or if the TV is particularly large and heavy.

Optimizing Your Viewing Experience:

Adjusting TV settings for the best picture:

To achieve the best picture quality, take some time to adjust your TV’s settings according to your preferences and room conditions. Consider factors such as brightness, contrast, color temperature, and sharpness. You may also explore picture presets and settings designed for specific types of content, such as movies, sports, or gaming.

Proper placement of speakers and audio equipment:

The placement of speakers and audio equipment can significantly impact your overall viewing experience. If you’re using a soundbar, place it directly below the TV or mount it on the wall for optimal sound quality. For a home theater system, follow the manufacturer’s guidelines for speaker placement to create an immersive surround sound experience.

Managing cables and clutter for a clean setup:

To maintain a clean and organized setup, take steps to manage cables and other electronic components. Use cable ties or clips to bundle cords together and keep them out of sight. Consider using a cable management system, such as a cable raceway or a cable organizer, to conceal wires and maintain a tidy appearance.

Incorporating smart home devices and accessories:

Enhance your TV viewing experience by integrating smart home devices and accessories, such as streaming devices, voice assistants, and smart lighting systems. These devices can help you create a seamless and connected entertainment setup, making it easier to control and customize your viewing environment.


By understanding the importance of TV dimensions, learning how to measure a TV accurately, and considering factors like viewing distance, screen resolution, and room layout, you’ll be well-equipped to choose the perfect TV size for your space. Remember to pay attention to the installation process, whether to wall mount your TV or place it in a cabinet. Optimize your viewing experience by adjusting settings and incorporating additional audio and smart home components. Considering all these factors will ensure that you create the best possible home entertainment setup, providing endless hours of enjoyment for you and your loved ones.
